Embodiment Construction

[0029]FIGS. 1 and 2 disclose a preferred embodiment of a shift lever assembly 1 with a housing 2, a shift lever unit 3, cable unit 4 and sensor assembly 6 that when mounted form an assembled shift lever assembly 1 as shown by FIG. 1. The shift lever unit 3 comprises a shift lever 31 and detent plunger 32 that are mounted in an overmold 33 extending towards a ball 34 of a ball joint with pegs 35. Said shift lever unit 3 is mounted in the cable unit 4 so that the ball 34 rests at a seat of the cable unit 4 and is arranged to pivot about a first axis α (see FIG. 6b). The shift lever 31 is arranged to pivot between a number of positions in a first gate, each position corresponding to a mode of transmission. Furthermore, the cable unit 4 is held by a base 21 of the housing 2 by means of receiving portions 25 that allow the cable unit 4 to pivot. Also provided is the sensor assembly 6 having a first member carrier 65, connected to the shift lever 31, and a carrier body 60 that is displace...
